Application filed June 13, 1917. Serial No. 174,477.

To all whom it may} concern:

Be it known that I, HENRY J. EDLUND, a citizen of the United States, and a. resident of Burlington, in the county of Chittenden and State of Vermont, have invented a new and Improved Broom-Making Machine, of

which the following is a full, clear, and exact description.

This invention relates to machines for making brooms and has for an object the provision of an improved construction for making brooms of a type shown in my Patent Number 1,200,326, issued October 3, 1916.

Another object in view is to provide an improved construction and arrangement of parts whereby there will be successive stages of operation beingdone simultaneously, the steps or times of movement being evenly divided, whereby an even continuous output is provided for.

Another object in view is to provide a machine for automatically clamping, shaping and riveting the brooms after the parts have been substantially properly arranged in position manually. 7

A further object in view,more specifically, is the provision of an improved arrangement of parts whereby the moving elements are driven from a single power member and are thereby more evenly timed so that the successive operations may be carried out in certain timed intervals and each broom operated on for the same length of time so as to produce continually the'same quality of finished product.

In the accompanying drawings:

Referring to the accompanying drawings by numerals, 1 indicates a power member of any suitable kind for supplying power to the drive shaft 2 supported in suitable bearings carried by'the frame 3. The frame 3 is provided with a top or table 54 and with a number of braces 5, the particular detail structure of these parts beingcapable of change and rearrangementto a considerable extent without departing from the spirit of the invention, as these parts form merely proper supports for the other working part of the machine. The power member 1 is conneoted to the shaft 2 by a clutch 6 which may be thrown in or out as desired by the operation of lever 7 so that the power is easily controlled and is'used only when desired. In order to turn the power on or off at a point nearer the operating parts a rod 8 is pivotally connected with lever 7 andis also pivotally connected with lever 7, which lever extends outwardly, as shown in Figs. 1 and 4, whereby an operator may be near the working parts of the machine and at the same time control the clutch. Lever 7 is pivotally supported by a suitable bracket 10 secured to the top or table 4.

The table 4 is provided with an enlarge ment 11 forming a journal member for the vertical shaft 12 (Fig. 4) so that the shaft may be held in properposi-tion while sup porting the rotatable wheel structure or turn-table 13. The turn-table 13 is rigidly secured in any desired m-anner, as for instance by a key, to shaft 12 and bear against an enlargement 14, which enlargement in turn bears against a: cone or washer 1-5 resting in the roller bearings 16. The roller bearings 16 operate on a bearing member 17 which bearing member may be raised or lowered through a proper movement of the set screws 18 inorder to sllghtly ralse or lower the turn-table 13 f and parts carried there by. The turntable'13 carries'a number suitable material in the various holders 19,

it is necessary that the turn-table 13 rotate step by step and after each movement remain stationary for a given period. In order to accomplish this the structure shown more or less in detail in Figs. 2 and 18 is utilized. When the clutch 6 has been thrown in power will be transmitted to shaiit 2 for rotating the shaft and, consequently, rotating the worms 20 and 21, which w'ornis mesh with the respective worm wheels 22 and A gear wheel 24 is also rigidly secured to shaft 2 so as to be rotated thereby, said gear wheel meshing with a pinion 25, as shown in Figs. 3 and 4, whereby said pinionis rotated and, consequently, rotates its shaft A. link 27 is eccentrically journaled at 28 on shaft 26 and as pinion r0- tates said link 27 will move upwardly and downwardly. The upper end of link 27 is pivotally connected with a lever 29 journaled at 30 on the: bracket 31, whichbracket also supports the pinion 25. The up and down movement of lever 29 operates through pin 32 extending into the slot 33 for causing the rod 34, which is rigidly secured to pin 32, to -move'upwardlyand downwardly, the.

downward movement being against spring 35 surrounding the upper part of rod 34. The upper part of rod 34 is reduced so asto present a shoulder in order that the table 36 may be rigidly clamped to the rod .34 by a nut 37. The table 36 extends preferably beneath three of the holders 19, as shown in Fig. 2, so that-when the broom corn is first placed in the holder it will rest on this platform or'tableand may be acted on by this table until thejaws of'the holders have been closed, as hereinafter fully described. It will be understood that theib-room' corn does not rest directly upon the table 36 but upon a supporting plate 38 carried by rods 39' which are acted on directly by the table36.

From the above it will be seen how power is transmitted tothe worm gears 22 and 23 and" also to mechanism for raising and lowering the table 36 inorder toproperly ad just the broom corn. In order to rotate the turn-table 13 in addition to accomplishing the-purposesjust mentioned, power is transmitted from the worm gear 22 to-shaft=4O imported by suitable brackets 41 and 42. Aaspiral gear 43-is rigidly secured to the shaft 40, as shown in Fig. 1,'said spira1 gear meshing with a second spiral gear 44, which last mentioned spiral gear is rigidly secured to a vertical shaft 45 carrying adisk 46 at its lower end, as shown in Figs. 2'and218. The disk-46 is' held in proper position "by. a bracket 47 and as it rotates it moves a link 48 and said I link is pivotally connected to said disk at a point distant from the'center so that as the disk rotates-the linkwvilhbe moved in a back and forth movement longitudinally. The 0 posite end of the link 48 to that connecte' with disk 46 is pivotally connected with an a-rm49 loosely j ournaled on the shaft 12 andcanrying a pawl 50 at its outer end. Pawl 50 is preferably maintained in proper position by the action of gravity, though a spring may be used if desired for causing the pawl to normally remain in contact with the horizontal wheel 51, which horizontal wheel is rigidly secured in any desired manner to the shaft 12.

The horizontal wheel 51 is provided with a plurality of stops 52 having a beveled side and a vertical side so that when the arm 49 moves in one direction the pawl 50 may freely slide over the stop but when said pawl is moved in the opposite direction the wheel 51 and parts connected thereto will be moved therewith. There is provided one stop 52 for each of the holders 19 and they are spaced an equal distance apart in a similar manner to the holders so that upon one half of a revolution of the disk 46 the wheel 51 and parts connected thereto will be stationary and on the other half of the revolution of disk 46 the wheel 51 and parts connected thereto, including the holders 19. will move. By this construction and arrangement if the drive shaft 2 is allowed to rotate at a constant speed there will be the same time occupied during the movement of the turn-table 18 as during the stationary period thereof. In order to lock the wheel 51, turn-table 13 and associated parts, the wheel 51 is provided with a notch 53 at each stop 52, into which the locking pin snaps by reason of the action of spring 55, as shown in Fig. 18. The pin 54 is guided by suitable bearings 56, one of said bearings acting as a stop for spring 55 so that the spring 55 will continually urge the pin 54 to the position shown in Fig. 18. The opposite sides of the point of the pin 54 are beveled so that when the wheel 51 begins to move the pin may back out of the notch and readily slip into the next notch.

The turn-table 13 is supported by shaft 12 so as to rotate as heretofore described, said shaft being supported in a suitable journal box 12 connected with or forming part of the brace 5. As shown in the drawing, the turn-table 13 is divided into eight sections or segments, though it may be divided into a greater or less number without departing from the spirit of the invention. This turn-table has connected therewith eight holders 19, as shown in Fig. 1. these holders being of identical construction and designed to be operated on in different ways during the successive steps of operation of the machine so as to evenly arrange the broom corn, compress the broom corn and apply retaining clips and rivets thereto. The first stage of operation is where the broom corn is placed into the holder 19 of section 57. This section rotates; step by step until it finally moves back to the position shown in Fig. 1. The remaining sections 58, 59, 6O, 61, 62, 63 and 64 are identically constructed with the section 57 and the holders 19 therein are also idei'iticallv constructed with the holder 19 in section 57, but as shown in Fig. 2 the various mechanisms associated with the holders are in different stages of operation.

Each of the holders 19 is provided with jaws 65 and'66, aw 65 being bolted or otherwise rigidly securod to the turn-table 1?) While jaw 66 is movable radially toward and from jaw 65. When the broom corn is first placed into the holder 19 in section 57 it will be arranged substantially as shown in Fig. 4, with the lower ends of the straws in different planes. In order to even up these straws the table 36 is moved upwardly and downwardly as heretofore described so an to cause all the straw to move into proper alinement. This up and down movement of the table 36 acts on the broom corn from the time it is placed in the holder in section 57 until said holder has passed the position of section 59. The shaking table or plate 36 not only evens the ends at the bottom but acts to shake down all straw that is short, making all ends of straw. short or long, even at the bottom. 'When passing from the position of section 59 to the position of section the broom corn will have assumed the position shown in Fig. with the lower edge perfectly straight and also the upper edge straight if the broom corn has been properly cut. The table 36 acts on the supporting plate 38, which supporting plate is held in position preferably by several rods 39 slidingly mounted in sockets 39, formed in jaw 65, said rods being surrounded by a spring 39" for resiliently forcing said plate downwardly. as shown in Fig. 19.

Before the broom corn is placed in the holder 19 a band member 67. shown in (ic tail in Fig. 22, is placed loosely in the holder, each part thereof comprising a strip of metal formed with an inwardly depressed 1 section 68 having apertures 69 arranged therein. Along one edge of each part of the band are spurs 70 adapted to fit into notches 71 in the jaws and'66 (Fig. 28).

Each of the bands 67 is also preferablv I provided with a lug 72 fitting in the notch in the opposite band so as to provide an overlapping section at the ends. The bands 67 are loosely arranged in position manually and then the broom corn is forced inani'ially into position, substantially as shown, in Fig. 4. The broom corn is reasonably loose when placed in this position but is guarded against catching in the depressions in the bands'67 by the plates 73 and 74 (Figs. 21 and 22),
